TECHNICAL FIELD

The present invention disclosed herein relates to a heath care or wellness system having proximity-based neighbor device wake-up and automatic user identification function, a method of logging and analyzing a user's daily life activity history, and a method of automatic alerting and reminding a user's abnormal activity pattern.

BACKGROUND ART

With the recent rapid development of an economic level, a desire to enhance the quality of life increases and such a desire is represented as great interest in personal health or wellness.

With the significant enhancement of overall health and medical treatment conditions of medicine and medical devices including medical knowledge, a national health level has been steadily improved. For example, an average lifetime has been extended but, a chronic degenerative disease such as an adult disease has increased rapidly due to a change in lifestyle such as industrialization, aging or urbanization.

As represented in a recent research result that various chronic degenerative diseases are related to a personal lifestyle, everybody agrees that the best way to maintaining personal health is steady management and usual examination.

In particular, health related content based on information communication infrastructure and information communication technology is recently spread, so it may be seen that an information technology-bio technology (IT-BT) hybrid technology age has arrived.

Anybody may carry or wear a high-performance micro computer through a rapid technological development, and with the recent, broad distribution of smart phones or smart watch (wearable devices) and the construction of a mobile network, a ubiquitous age in which a user may connect to a network anytime or anywhere has arrived. For example, with the approach of a ubiquitous age that is a network age that has high-performance computing-power devices such as wearable devices (such as smart watch) with smart phones and uses theses devices arrives, service areas that are typically provided are also expanded gradually in range.

Silver industry and medical service industry fields develop in order to keep pace with the aging society, and thus if a ubiquitous wearable technology and a health care technology are combined, a patient may manage his or her health for oneself at home even if he or she does not necessarily go to the hospital. With the technological development and an increase in lifetime, a medical service industry field has further developed and devices for effectively providing such a medical service have been invented.

Typically, since most of medical services fail to utilize the advantage of a high-performance mobile terminal and most of users that use the medical services are old, there is a difficulty in operating an interface to a mobile terminal and thus there is no dramatic effectiveness.

For example, in the case of a dementia patient, he or she has a difficulty in managing his or her health for oneself without a guardian and in some cases, a guardian may not take care of the dementia patient due to the reason for making ends meet. Accordingly, there is a need for a system that provides a big help with a user's daily activity even without a complex user's operation.

Also, when a medical service is provided by using a communication scheme such as Wi-Fi, 802.15.4 MAC, or Bluetooth scheme, there is a limitation in that the precision in location identification of a mobile terminal in a narrow area of 0.1 m to 3 m is low.

That is, a complex calculation is needed in order to accurately measure the location of a mobile terminal, but related art has a limitation in performing the calculation by using a low-power micro control unit (MCU) and thus there is a limitation in that since the related art may not accurately identify the location when there is a wire wall or an obstacle, it is not appropriate for applying to an indoor medical service.

Also, when providing a medical service to a portable personal mobile terminal, the related art has a limitation in that power consumption significantly increases.

That is, when a location is identified by using a general RF signal strength, the frequent transmission and reception of RF signals are needed between a fixed device and a device for identifying a location in which case, a power consumption amount is significantly greater than a fundamental power consumption amount because power consumption increases in proportion to a increase in the number of times transmission and reception are performed.

A limitation that may appear when providing various services by using mobile terminals performing short-range communication is that the power consumption of a portable terminal is great because an electric wave needs to be continuously transmitted to around the portable terminal in order to monitor the approach of another terminal that attempts to establish a communication network. This operation reduces the charging and replacement cycle of a battery and causes significant inconvenience in use.

FIG. 1 shows a health care system including proximity-based neighbor device wake-up and automatic user identification function according to the present invention.

Referring to FIG. 1, a health care system 1000 including proximity-based neighbor device wake-up and automatic user identification function according to the present invention includes a health or wellness service unit 1100, a user terminal 1200 and an operator server 1300.

The health or wellness service unit 1100 measures a biological signal due to the electrical change, biochemical change, physical momentum, environmental change of a body on or in the vicinity of a subject body. In this case, a measured biological signal is transmitted to the user terminal 1200 by using proximity-based neighbor device wake-up and automatic user identification function.

In this example, the biological signal means multiple medical data such as a blood pressure, pulse rate, electrocardiogram, body temperature and weight of a subject body.

Being transmitted by using proximity-based neighbor device wake-up and automatic user identification function means that measured medical data is automatically transmitted to the user terminal 1200 even if a subject does not separately operate the user terminal 1200.

For example, even though a user does not perform a separate operation on the user terminal 1200, the user terminal 1200 automatically becomes a wake up state in response to a service advertising message transmitted from the health or wellness service unit 1100.

Also, when a corresponding service is preset on the user terminal 1200, a user identification (ID) and measured data may be mutually exchanged by using a direction prediction index and the physical distance between the health or wellness service unit 1100 and the user terminal 1200 even without a user operation.

The user terminal 1200 performs bidirectional communication with the health or wellness service unit 1100, receives the biological signal measured from the health or wellness service unit 1100 and further transmits an ID unique to the user terminal 1200 and an received signal strength indication (RSSI) to the health or wellness service unit 1100.

In this case, the user terminal 1200 uses a terminal that may perform location-based wireless communication, such as a watch and glasses capable of implementing location-based wireless communication, in addition to a mobile terminal including a smart phone, a smart pad, an iPod, and a personal digital assistant (PDA),

The operator server 1300 performs bidirectional communication between the health or wellness service unit 1100 and the user terminal 1200 through a network, analyzes finally measured data transmitted from the health or wellness service unit 1100 to manage health information on a subject, and provides requested health information for a user when there is a health information request from the user terminal 1200.

In this example, the finally measured data means data transmitted with a packet structure that includes information on a user ID, measured data (such as a blood pressure, blood sugar, and weight), a measured time, and a measuring device ID.

Although the network uses an IEEE 802.15.4 MAC, Bluetooth communication or Wi-Fi communication protocol in the present invention in order to construct a wireless sensor network, it may also apply variously depending on a technical development without limitation to the protocol above.

The configuration and function of the health or wellness service unit 1100 and the user terminal 1200 that form the important components of the present invention are described below in detail with reference to FIGS. 2A and 2B.

FIG. 2A specifies the configuration of the health or wellness service unit shown in FIG. 1.

Referring to FIG. 2A, the health or wellness service unit 1100 of the present invention includes an input unit 1110, a power supply unit 1120, a storage unit 1130, a wireless communication unit 1140, a radio frequency (RF) antenna 1150, a low frequency (LF) transmission unit 1160, an LF antenna 1170, and a main control unit 1180.

The input unit 1110 is used for obtaining medial data on a subject and may use a button input type, a pen input type, and a touch input type.

The power supply unit 1120 plays a role of supplying power to the main control unit 1180, the wireless communication unit 1140, the RF antenna 1150, the LF transmission unit 1160, and the LF antenna 1170.

Medical data on a subject including various programs and measured biological signals needed for the operation of the main control unit 118 is stored in the storage unit 1130.

The wireless communication unit 1140 plays a role of processing a signal transmitted and received through the RF antenna 1150 and use a communication network such as an Ethernet, wireless broadband internet (WiBro), Wi-Fi, world interoperability for microwave access (WiMAX), high speed packet access (HSPA), code division multiple access (CDMA), or Bluetooth network.

The RF antenna 1150 transmits and receives a signal through RF communication with an external communication device and in this case, an IEEE 802.15.4 MAC, Blue tooth communication or Wi-Fi communication protocol may be used as a protocol of a network applied to wireless communication.

The LF transmission unit 1160 is used for transmitting data to an external user terminal 1200 and generates a wake-up signal waking up the user terminal 1200 for implementing low power and an LF signal for the location identification of the user terminal 1200.

The LF antenna 1170 transmits and receives a signal through LF communication with the external user terminal 1200 at a low frequency band of 10 kHz to 150 kHz.

The main control unit (MCU) 1180 controls the input unit 1110, the power supply unit 1120, the storage unit 1130, the wireless communication unit 1140, the RF antenna 1150, the LF transmission unit 1160, and the LF antenna 1170.

FIG. 2B specifies the configuration of the user terminal shown in FIG. 1.

Referring to FIG. 2A, the user terminal 1200 of the present invention includes a charging unit 1210, a storage unit 1220, a wireless communication unit 1240, an RF antenna 1250, an LF reception unit 1260, an LF receiver antenna 1270 and a main control unit 1280.

The charging unit 1210 includes a battery to fill charges so that the user terminal 1200 may operate without a lack of charges.

Various programs needed for the operation of the main control unit 1280 and medical data transmitted from the health or wellness service unit 1100 are stored in the storage unit 1220.

The wireless communication unit 1240 plays a role of processing a signal transmitted and received through the RF antenna 1250 and may use a communication network such as an Ethernet, wireless broadband internet (WiBro), Wi-Fi, world interoperability for microwave access (WiMAX), high speed packet access (HSPA), code division multiple access (CDMA), or Bluetooth network.

The RF antenna 1250 transmits and receives a signal through RF communication with an external communication device and in this case, an IEEE 802.15.4 MAC, Blue tooth communication or Wi-Fi communication protocol may be used as a protocol of a network applied to wireless communication.

The LF transmission unit 1260 receives a wake-up signal for implementing low power transmitted by the external health or wellness service unit 1100 and an LF signal for the location identification of the user terminal 1200.

When the LF receiving unit 1260 senses an LF signal operating at lower power of several micrometers um and generates certain wake-up interrupt in response to a sensed LF signal, the main control unit 1280 changes the wireless communication unit 1240 usually having a sleep state to a wake-up state, according to the interrupt.

In this case, the LF signal is transmitted at a frequency band of 10 kHz to 150 kHz, the distance between a signal transmitter and a signal receiver is 1 m to 10 m, and it is possible to identify the physical distance and direction between the health or wellness service unit 1100 and the user terminal 1200 3-dimensionally (x, y, z) by using the signal.

The LF reception unit 1260 measures an RSSI corresponding to a received signal when an LF signal for the 3-dimensional location identification of the user terminal 1200 from the health or wellness service unit 1100.

A measured RSSI is transmitted to the health or wellness service unit 1100 through the wireless communication unit 1240 according to the certain control of the main control unit 1280.

The LF receiver antenna 1270 transmits and receives a signal through LF communication with the external health or wellness service unit 1100.

The main control unit (MCU) 1280 controls the charging unit 1210, the storage unit 1220, the wireless communication unit 1240, the RF antenna 1250, the LF reception unit 1260, and the LF receiver antenna 1270.

FIG. 3 represents the sequence diagram of a protocol for providing a health care service between the body index measuring unit and the user terminal of the present invention.

A method of providing the health care service between a plurality of user terminals 1200 a and 1200 b and the health or wellness service unit 1100 of the present invention is described with reference to FIG. 3.

First, when first and second user terminals 1200 a and 1200 b are turned on and are adjacent to each other, the health or wellness service unit 1100 transmit wake-up signals to the first user terminal 1200 a and the second user terminal 1200 b, respectively in steps a10 and b10.

Next, the first and second user terminals 1200 a and 1200 b sense wake-up signals through each LF receiver 1260, then generate certain interrupt and change each state from an usual sleep state to an wake-up state in steps a20 and b20.

Next, when a service event occurs, the health or wellness service unit 1100 transmits a corresponding service advertising message to the first and second user terminals 1200 a and 1200 b in steps a40 and b40.

In this example, the service event means a case where there is a service advertising message to be provided for a user.

Next, the first and second user terminals 1200 a and 1200 b transmit IDs unique to each of the terminals, RSSI and received-signal direction information to the health or wellness service unit 1100 in steps a50 and b50.

Next, the health or wellness service unit 1100 compares RSSI values and received-signal direction values transmitted from the first and second user terminals 1200 a and 1200 b, comprehensively analyzes the physical distances between the user terminals and the health or wellness service unit and the states of the user terminals and selects a user terminal satisfying an optimal communication state.

As an example, when a first RSSI value transmitted from the first user terminal 1200 a is larger than a second RSSI value transmitted from the second user terminal 1200 b and other communication states are the same, the health or wellness service unit 1100 selects the first user terminal 1200 a.

Next, the health or wellness service unit 1100 transmits measured data to a selected first user terminal 1200 a in step a70.

Lastly, the first user terminal 1200 a checks a response message informing that measured data is received in step a80, and the second user terminal 1200 b checks a response message informing that measured data is not received in step b80.

The execution state of each step of FIG. 3 is described in detail based on the operation states of the health or wellness service unit and the user terminals with reference to FIGS. 4a and 4 b.

FIG. 4A represents a state diagram related to the operation of the health or wellness service unit of the sequence diagram of the protocol of FIG. 3.

Referring to FIG. 4A, when an observer presses the start switch of the health or wellness service unit 1100 in order to measure physical indexes such as a blood pressure and weight of a subject, the health or wellness service unit changes from an initial IDLE state to a service usage state.

In the service usage state, the health or wellness service unit 1100 transmits a wake-up signal and a service advertising message to the user terminal 1200.

The health or wellness service unit 1100 receives an ID unique to a terminal and an RSSI from the user terminal 1200 and checks the ID and location of the user terminal 1200.

When a service request signal is received from the user terminal 1200, the health or wellness service unit 1100 changes to a service success state and transmits requested, measured data to the user terminal 1200.

When communication is not made with the user terminal 1200, the health or wellness service unit 1100 changes to a service failure state, transmits a service failure message to the user terminal 1200, and changes to an IDLE state through initialization.

FIG. 4B represents a state diagram related to the operation of the user terminal of the sequence diagram of the protocol of FIG. 3.

Referring to FIG. 4B, when the user terminal 1200 receives a wake-up signal and an LF signal of a LF band from the health or wellness service unit 1100, the user terminal 1200 generates wake-up interrupt in response to a sensed wake-up signal and changes from an usual sleep state to a wake-up state.

In the wake-up state, the user terminal 1200 measures an RSSI corresponding to a received LF signal and enables it to be used for location sensing.

The main control unit MCU 1280 that is in a wake-up state checks whether a service is activated, and when the service is in an inactive state, the MCU initializes wake-up interrupt and inactivates the wireless communication unit 1240 to set back to an initial IDLE state.

On the contrary, when the MCU 1280 checks whether a service is in an active state and if positive, the MCU changes the wireless communication unit 1240 to the active state to be able to receive a service advertisement message from the health or wellness service unit 1100, after which the user terminal 1200 changes to a service request state.

In the service request state, the user terminal 1200 transmits an RSSI corresponding to an LF signal and an ID unique to a terminal to the health or wellness service unit 1100.

When a response message received from the health or wellness service unit 1100 includes measured data, the user terminal 1200 changes to a service activation state and displays measured data.

On the contrary, when a response message received from the health or wellness service unit 1100 does not include measured data or there is no response for a preset time period, such as in a time-out situation, the user terminal 1200 changes to a service inactivation state to initialize wake-up interrupt and inactivates the wireless communication unit 1240 to set back to an initial IDLE state.

In the following, a user activity pattern management system according to an embodiment of the present invention is described. The user activity pattern management system according to an embodiment of the present invention includes terminals installed at devices provided for a user activity area and a portable terminal that receives activity data from a terminal according to a user's usage action to the device, and collects user activity pattern data. The terminal senses that user's device usage and transmits a wake-up signal to a portable terminal, and the portable terminal changes from a sleep mode to a wake-up mode according to a wake-up signal and receives activity data directly from the terminal by using proximity-based neighbor device wake-up and automatic user identification function.

According to the user activity pattern management system according to an embodiment of the present invention, it is possible to identify a user activity pattern by only performing an ordinary activity without a need for a user to perform a complex operation on a portable terminal. Also, since the portable terminal does not always operate in order to monitor a user's ordinary activity but only when a user uses a device, the portable terminal wakes up so that user activity pattern data may be obtained, it is possible to minimize the power consumption of the portable terminal and the terminal installed at the device and it is possible to extend a battery charging cycle or replacing cycle and thus enable long-term use.

The user activity pattern management system according to an embodiment of the present invention may include activity data, a portable terminal's ID and device usage time information in one data packet to collect user activity pattern data. The portable terminal's ID 1:1 corresponds to a user ID and it may be said that the portable terminal's ID represents the user ID. The user activity pattern data formed as a single data packet may be transmitted to the personal mobile terminal of a user or a guardian or an external device such as a hospital server and it is possible to comprehensively check user activity pattern data on a user through a corresponding external device.

In an embodiment of the present invention, the portable terminal may provide a notification function at a time corresponding to each schedule on a schedule management list according to a preset schedule management list, and generate an alarm signal or transmit an alarm message to an external device when the schedule management list does not match user activity pattern data or an abnormal activity pattern is sensed. According to an embodiment of the present invention, it is possible to help a user to perform an ordinary activity according to the schedule management list, and when a user does not act according to the schedule management list, it is possible to generate an alarm and provide a notice for a user or transmit an alarm message to an external device. Accordingly, it is possible to manage a user activity pattern by providing a notice for a guardian or a medical specialist.

In an embodiment of the present invention, the portable terminal may generate a wake-up event at a time corresponding to each schedule of the schedule management list, changes to a wake-up mode according to the wake-up event, and transmit a control message to a terminal of a device side corresponding to each schedule of the schedule management list, the terminal installed at a device may receive a control message, sense the approach or the portable terminal, communicates with the control unit of the device and automatically operate the device according to the control message. According to an embodiment of the present invention, since a device may automatically operate as scheduled only by an action that a user carrying a portable terminal approaches the device corresponding to a schedule on a schedule management list, it is possible to perform an activity as scheduled by using a device even if it is complicated to operate the device.

In an embodiment of the present invention, a guardian or a medical specialist may transmit an SMS command message to a user's mobile terminal by using a mobile terminal, the user's mobile terminal may check a meta script of the SMS command message and transmit a control command signal corresponding to a command to a portable terminal, and the portable terminal may modify a schedule management list according to the control command signal, transmit a control message for automatically operating a device to a terminal of the device or transmit user activity pattern data to a user's or guardian's mobile terminal or a hospital server. According to an embodiment of the present invention, a user's guardian or a medical specialist may remotely manage a user activity pattern though a mobile terminal or outside the hospital.

FIG. 5 is a schematic diagram of a user activity pattern management system according to an embodiment of the present invention; Referring to FIG. 5, a user activity pattern management system 100 according to an embodiment of the present invention includes a plurality of terminals 110, a portable terminal 120, and an external device 130. Terminals 11 to 13 are installed at devices 21 to 23 that are provided in a user activity area 10.

The activity area 10 may be a space such as a user's residential space, office or fitness center. For example, when the activity area 10 is a residential area, the device 20 may be devices needed for daily life, such as a refrigerator, a toilet bowl, a medicine storage drawer, a microwave oven, a gas range, a TV, a phone or a water purifier. As another example, when the activity area 10 is a fitness center, the device may be sports equipment such as a treadmill, a cycle or a bench press.

Terminals 11 to 13 may be installed on the external surfaces of or inside corresponding devices 21 to 23 or may also be installed at locations adjacent to corresponding devices 21 to 23. The terminal 110 includes a sensor 111 (of FIG. 8) that senses whether a user uses the device 20. When a user carrying the portable terminal 120 uses the device 20, the terminal 110 senses that the user uses the device and then transmits a wake-up signal to the portable terminal 120.

The portable terminal 120 changes from a sleep mode to a wake-up mode according to the wake-up signal and receives activity data directly from the terminal by using proximity-based neighbor device wake-up and automatic user identification function. The portable terminal 120 receives activity data from the terminals 11 to 13 according to a user's usage action to the device 20 and collects user activity pattern data. The portable terminal 120 may be a wearable terminal that is provided with a small size and light weight so that a user may wear and carry it.

FIG. 6 shows a portable terminal configuring a user activity pattern management system according to an embodiment of the present invention. As in an embodiment shown in FIG. 6, the portable terminal 120 may be provided with a form similar to a general wrist watch that includes a housing 120 a that has a display unit 121, and a watch strap 120 b that is connected to both sides of the housing. However, the form of the portable terminal is not limited to that shown in FIG. 6

FIGS. 7A to 7C show a portable terminal configuring a user activity pattern management system according to another embodiment of the present invention. The portable terminal 120 may be provided e.g., a pass form as shown in FIG. 7A, installed on glasses, clothing or belt as shown in FIG. 7B, or installed at an external device 130 such as a mobile phone as shown in FIG. 7C.

Referring back to FIG. 5, the portable terminal 120 may perform short-range communication with the terminal 110 through LF transmission and reception, change from a sleep mode to a wake-up mode according to a wake-up signal received from the terminal 110, and receive activity data corresponding to a usage action from the terminal 110. As an embodiment, activity data may include a terminal ID, a device ID, and the ON/OFF operation of a device.

The portable terminal 120 may use activity data received from the terminal 110 to collect user activity pattern data. As an embodiment, the user activity pattern data may include activity data, a portable terminal ID and usage time information. The portable terminal 120 may include portable terminal 120 ID, activity data and device operation time information corresponding to activity data in one data packet to collect the user activity pattern data.

The external device 130 may be a user's or guardian's personal mobile terminal such as a smart phone. The external device 130 may operate in linkage with the portable terminal 120. For example, the external device may collect user activity pattern data from the portable terminal 120 to store or display it on a screen. As another example, the external device 130 may transmit a control command signal that includes a command to transmit a schedule management list to the portable terminal 120, automatically operate the device 20 or request the transmission of user activity pattern data or modify the schedule management list.

The external device 130 may use wireless communication functions such as WiFi and Bluetooth to transmit user activity pattern data or an alarm message to an external mobile terminal of a guardian located outside the activity area 10 or a hospital server or receive an SMS command message therefrom and the control command signal to the portable terminal 120. When there is no external device 130 in the activity area 10, the portable terminal 120 may transmit and receive information to an external mobile terminal of a guardian outside the activity area 10 or a hospital server.

As an embodiment, the portable terminal 120 may provide an alarm function at a time corresponding to each schedule on a schedule management list according to a preset schedule management list. The portable terminal 120 checks whether the schedule management list matches the user activity pattern data and when the schedule management list does not match the user activity pattern data or an abnormal activity is sensed through the activity pattern data, it is possible to generate an alarm signal or transmit an alarm message to an external device 130 located in the activity area 10 or a hospital server or a mobile terminal of a guardian located outside the activity area 10.

FIG. 8 is a schematic diagram of a terminal configuring a user activity pattern management system according to an embodiment of the present invention. Referring to FIGS. 5 and 8, the terminal 110 includes a sensor 111, a control unit 112, an LF transmitter 113, a power stage 114, a wireless transceiving unit 115, and a power supply unit 116. The control unit 112 controls various functions of the sensor 111, the LF transmitter 113, the power stage 114, and the wireless transceiving unit 115. As an embodiment, different terminals 11 to 13 may also include the same sensors 111 or different types of sensors 111.

When a user carrying the portable terminal 120 uses the device 20, the sensor 111 senses user's usage action to a corresponding device 21, 22 or 23. The sensor 111 may be e.g., a hall sensor, a touch sensor such as a piezo sensor, a loadcell, a photo sensor, a thermal sensor, an angular sensor or an ammeter. For example, in the case of a refrigerator or a medicine storage drawer, it is possible to a user's usage action by installing a touch sensor on a knob, and in the case of a TV or a microwave oven, it is possible to sense a home appliance usage action by installing an ammeter. For example, when using the ammeter, it is possible to sense a usage action by checking a current flowing through a power supply when the terminal 110 operates with a constant power supply, and when there is no constant power supply, it is possible to attach a battery tag and sense a usage action by checking a current flowing through a tag in operation.

The terminal 1110 is maintained in a low power standby mode when sensing a user's usage action, and does not attempt to communicate with the portable terminal 120 in this case. If the sensor 111 senses a user's usage action, the terminal 110 attempts to communicate with the portable terminal 120. As the sensor 111 senses the user's usage action, the LF transmitter 113 transmits a wake-up signal to the portable terminal 120 through the transmission antenna 113 a. The LF transmitter 113 uses a low-power LF signal having an LF band such as 10 to 150 KHz to perform short-range communication with the portable terminal 120.

When there is a plurality of users individually carrying and using the portable terminal 120 near the device 20 in the activity area 10, the terminal 110 may use a low-power LF signal to predict the distance of the portable terminal 120 wore by adjacent users by using a low-power LF signal, and select the most suitable portable terminal 120, which is estimated as using the device 20, based on the distance.

The power stage 114 sets the terminal 110 to a low-power standby mode until the sensor 111 senses a user's usage action, and when the sensor 111 senses the user's usage action, the power stage raises power and operates the LF transmitter 113. When activity data is transmitted from the terminal 110 to the portable terminal 120, the power stage 114 again operates the terminal 110 in a low-power standby mode until a new usage action is sensed.

The wireless transceiving unit 115 may transmit activity data corresponding to a usage action to the portable terminal 120 through radio frequency (RF) communication, and receive a control message from the portable terminal 120. The wireless transceiving unit 115 may communication with the portable terminal 120 by using e.g., a Bluetooth or WiFi scheme.

The power supply unit 116 supply direct current (DC) or alternating current (AC) power to the terminal 110. The power supply unit 116 may be provided as a 220 V constant power supply that is used for general home, or include a small battery when a constant power supply is not used. When the terminal 110 is installed in the device 20, the power supply unit 116 may receive some of power supplied to the device 20 through a socket from the device 20 and supply power to the terminal 110. Alternatively, the power supply unit 116 may be provided in a chargeable or replaceable battery type and also supply power to the terminal 110.

FIG. 9 is a schematic diagram of a portable terminal configuring a user activity pattern management system according to an embodiment of the present invention. Referring to FIG. 9, the portable terminal 120 includes a display unit 121, a processor 122, an LF receiver 123, a schedule management unit 124, a wireless communication unit 125, a state control unit 126, a time measurement module 127 measuring time information, a memory unit 128, and an alarm generation unit 129. The processor 122 controls various functions of the display unit 121, the LF receiver 123, the schedule management unit 124, the wireless communication unit 125, the state control unit 126, the time measurement module 127, the memory unit 128, and the alarm generation unit 129.

The display unit 121 may display the current date and time through an LCD screen similarly to the fundamental operation of a general wrist watch. As an embodiment, the display unit 121 may display the details of a corresponding schedule at a time corresponding to each schedule in order to provide the schedules of a schedule management list for a user.

The portable terminal 120 is maintained in a sleep mode until receiving a wake-up signal from the terminal 110, and does not attempt to communicate with the terminal except when transmitting a control message.

If the wake-up signal is received from the terminal 110, the portable terminal 120 changes from a sleep mode to a wake-up mode according to a received wake-up signal, communicates with the terminal 110, and receives activity data corresponding to a usage action from the terminal 110.

The LF receiver 123 receives the wake-up signal from the terminal 110 through the reception antenna 123 a. Like the LF transmitter 113, the LF receiver 123 may perform LF communication such as short-range communication of several centimeters to several dozens of centimeters through a 100 KHz to 130 KHz band. The portable terminal 120 receives activity data from the terminal 110 and may then change from the wake-up mode back to the sleep mode. The processor 122 may use activity data received from the terminal 110 to collect user activity pattern data. As an embodiment, the user activity pattern data may include activity data, an portable terminal ID and usage time information. As shown in FIG. 11, the processor 122 may include an ID 71 of the portable terminal 120, an ID 72 of the device 20, activity data 73 and operation time information 74 on a device corresponding to activity data in one data packet to collect user activity pattern data.

Referring back to FIG. 9, the schedule management unit 124 may provide an alarm function at a time corresponding to each schedule on a schedule management list according to a preset schedule management list. FIG. 10 shows an external device configuring a user activity pattern management system according to an embodiment of the present invention. Referring to FIG. 10, the external device 130 includes a schedule management application that may set or change a schedule management list through a user interface. The schedule management list set by the external device 130 is transmitted to the portable terminal 120. The schedule management unit 124 may display the details of a schedule on e.g., the display unit 121 as shown in FIG. 6 or additionally generate a sound or vibration providing the details of the schedule through the alarm generation unit 129 to provide the schedule for a user. The schedule management unit 124 may also update the schedule management list according to a schedule management message from the external device 130. A time corresponding to each schedule may be set as the start time of a corresponding schedule, before a certain hour therefrom, or a preset time.

The schedule management unit 124 may receive a schedule management message from the external device 130 and update the schedule management list according to the schedule management message. For example, when a user or guardian executes a schedule management application of the personal mobile terminal of a user or guardian, wireless communication is automatically established between the portable terminals, and when the schedule management list is updated through the application, the application transmits update information to the portable terminal 120. Then, the portable terminal 120 may reflect received update information to the current schedule management list, provide a notification function to a user according to an updated schedule management list and help with user's daily life.

In an embodiment of the present invention, the schedule management unit 124 may check whether user activity pattern data matches a schedule management list, and when negative, the schedule management unit may generate an alarm signal through the alarm generation unit 129 or transmit an alarm message to the mobile terminal of a guardian or a hospital server. For example, it is assumed that the schedule management list includes a medicine taking schedule. In this case, when a user opens a medicine storage drawer and takes a medicine at a time set for a corresponding medicine taking schedule, activity data is transmitted from the terminal 110 to the portable terminal 120 and the portable terminal 120 collects user activity pattern data representing when the user has taken a medicine.

When a medicine taking schedule has been provided but a user has not taken a medicine at a time set as a medicine taking schedule for some reasons such as forgetting, activity data is not transmitted from the terminal 110 to the portable terminal 120 since the sensor 111 installed at the medicine storage drawer senses a usage action. Thus, the medicine taking schedule will be left out from user activity pattern data on the portable terminal 120. In such a case, the schedule management unit 124 may determine that a schedule management list does not user activity pattern data, generate an alarm signal through the alarm generation unit 129, and transmit an alarm message to the mobile terminal of a guardian or a hospital server to provide a notice that a user such as a patient has not taken a medicine, for the guardian or a medical specialist.

The wireless communication unit 125 may receive activity data from the terminal 110 through RF communication. For example, the wireless communication unit 125 may broadcast request data including an ID of the portable terminal 120 in a wake-up mode according to a wake-up signal from the terminal 110. Accordingly, the wireless transceiving unit 115 of the terminal 110 may transmit activity data to the portable terminal 120 in response to the request data from the portable terminal 120.

The wireless communication unit 125 may transmit a control message from the terminal 110, transmit user activity pattern data to the external device 130 or receive a control command signal or a schedule management message from the external device 130. The wireless communication unit 125 may communicate with the terminal 110 and the external device 130 by using e.g., a Bluetooth or WiFi scheme.

The state control unit 126 may activate or inactivate the wireless communication function of the wireless communication unit 125 in e.g., a preset cycle. The processor 122 may broadcast a reception request message through the wireless communication unit 125 while a wireless communication function is activated by the state control unit 126. The external device 130 may transmit an acknowledgement message to the portable terminal 120 in response to the reception request message.

The processor 122 sets a wireless network in response to the acknowledgement message and transmits user activity pattern data to the external device 130 on a single data packet basis. When a wireless communication function is inactivated or the wireless communication function is activated but the acknowledgement message corresponding to the reception request message is not transmitted from the external device 130, the processor 122 may store user activity pattern data in the memory unit 129 and transmit accumulated user activity pattern data to the external device 130 when a wireless network is set.

FIG. 12 shows an external device configuring a user activity pattern management system according to an embodiment of the present invention. Referring to FIG. 12, the external device 130 may display user activity pattern data transmitted from the portable terminal 120 on a display screen. An embodiment shown in FIG. 12 represents an example of when user activity pattern data is transmitted to the mobile terminal of a user or guardian, but another external device such as a hospital server may also receive the user activity pattern data.

Referring back to FIG. 9, the schedule management unit 124 may generate a wake-up event at a time set for each schedule on a schedule management list. The portable terminal 120 changes to a wake-up mode according to a wake-up event and transmits a control message to the terminal 110 of a device 20 side corresponding to each schedule. To this end, the portable terminal 120 may further include an LF transmitter in addition to the LF receiver 123.

FIG. 13 is a schematic diagram of a terminal configuring a user activity pattern management system according to another embodiment of the present invention. When describing an embodiment shown in FIG. 13, components described in the embodiment shown in FIG. 8 are not described. The terminal 110 is installed in the device 20 and includes a communication interface that communicates with the control unit 30 of the device 20. The terminal 110 may receive a control message from the portable terminal 120, sense the approach of the portable terminal 120 and communicate with the control unit 30 of the device 20 through a communication interface 117 to automatically operate the device 20 according to the control message. The terminal 110 may communicate with the control unit 30 of the device 20 by using a serial communication scheme such as a universal asynchronous receiver/transmitter (UART), an inter-integrated circuit bus (I2C) or a serial peripheral interface (SPI), for example.

According to an embodiment of the present invention, if a user checks notification information provided according to a schedule management list by the portable terminal 120 and simply approaches the device 20 side according to a corresponding schedule, the operation of the device 20 is automatically performed according to a control message transmitted through wireless communication. Thus, it is possible to provide convenience for users who have difficulties in operating the device 20.

Referring back to FIG. 5, the external device 130 may receive an SMS command message from an external mobile terminal (not shown), read the SMS command message and transmit a corresponding control command signal to the portable terminal 120. The portable terminal 120 may modify a schedule management list, transmit a control message for automatically operating the device 20 to the terminal 110, or transmit user activity pattern data to the external device 130 or the external mobile terminal, according to a control command signal.

According to an embodiment of the present invention, only with a daily activity that a user simply does a job or opens the door of a refrigerator in order to take food out even if a user such as a patient does not perform a separate operation on the terminal 110 or the portable terminal 120, activity information is integrated with user information and an activity time to be collected as activity pattern data. Since user activity pattern data is compared with a schedule management list provided from a personal mobile terminal by the portable terminal 120 and a comparison result is transmitted to a guardian or family doctor in real time or regularly, the guardian or the family doctor may identify and analyze the activity pattern of patients living in a remote space and may quickly cope with an emergency situation.

The user activity pattern management system 100 according to an embodiment of the present invention may help a user that needs regular management such as personal health care management or medical data measurement or ordinary people that have important schedules or works. If the user activity pattern management system 100 according to an embodiment of the present invention is applied to a fitness center, a user may see with which sports equipment or how long he or she has exercised, through a smart phone, only with the operation of executing the schedule management application of the smart phone without a special operation.

If an exercise time for individual sports equipment is set by using a schedule management application of a smart phone and stored as a schedule management list, it is possible to use various pieces of sports equipment according to a schedule set through the notification function of the portable terminal 120, so it is possible to maximize an exercise effect. Also, when user activity pattern data does not match an exercise schedule, it is possible to provide corresponding information for a trainer in order to raise user activity pattern data utilization and it is possible to help a user to better manage an exercise schedule.

FIG. 14 shows an SMS command message transmitted to an external device configuring a user activity pattern management system according to an embodiment of the present invention. Referring to FIG. 14, the SMS command message includes a meta script 91, a command 92, an ID 93 of the device 20 to be controlled, a control command execution time 94, and a sustain time. As an embodiment, the external device 130 may identify the meta script of the SMS command message and transmit a control command signal corresponding to a command to the portable terminal 120.

In an embodiment shown in FIG. 14, ‘@@’ is used as an example of a meta script that may read the SMS command message, and ‘set’ or ‘get’ is used as a command. The ‘set’ is an example of a command representing that a schedule is modified on an external mobile terminal by using an SMS and the ‘get’ is an example of a command representing that a result processed according to a schedule is transmitted. However, according to a device to be controlled, the format of the SMS command message including a meta script or a command call may be variously changed.

The portable terminal 120 may modify a schedule management list, transmit a control message for automatically operating the device 20 to the terminal 110, or transmit user activity pattern data to the external device 130 or an external mobile terminal, according to a control command signal. According to an embodiment of the present invention, a guardian or a medical specialist may also control the portable terminal 120 or the device 20 remotely through an SMS message function.

FIG. 15 is a flow chart for explaining a user activity pattern management method according to an embodiment of the present invention. Referring to FIGS. 5, 8, 9 and 15, when a user carrying the portable terminal 120 does not operate the device 20 as in steps S1 and S2, the portable terminal 120 operates in a sleep mode and the device 110 installed at the device 20 operates in a low-power standby mode to minimize power consumption of the portable terminal 120 and the terminal 110.

When a user operates the device 20, the sensor 111 of the terminal 110 senses a user's usage action and transmits a signal for waking up the terminal 110 to the control unit 112 of the terminal 110, in step S3, and accordingly, the power stage 114 operates the LF transmitter 113 by the control of the control unit 112 and performs LF short-range communication to transmit a wake-up signal to the portable terminal 120, in step S4.

By the wake-up signal from the terminal 110, the portable terminal 120 changes from the sleep mode to a wake-up mode in step S5. In step S6, the LF transmitter 113 of the terminal 110 transmits key information including an ID of the device 20 or an ID of the terminal 110 to the portable terminal 120 and in step S7, the portable terminal 120 broadcasts key information including the ID of the portable terminal 120 in response to key information. That is, the portable terminal 120 transmits its own ID value to all terminals 20 therearound in order to find a terminal, which transmits a signal to the portable terminal, among terminals.

The terminal 110 checks key information from the portable terminal 120 in step S8 and transmits activity data corresponding to a user's device 20 usage action to the portable terminal 120 in step S9. In step S10, the portable terminal 120 stores activity data received from the terminal 110 and collects user activity pattern data. In this case, the portable terminal 120 may include an ID of the portable terminal 120, activity data and operation time information on a device corresponding to activity data in one data packet to collect the user activity pattern data, so it is possible to raise data utilization. Then, the terminal 110 changes back to the low-power standby mode in step S11 and the portable terminal 120 changes from the wake-up mode back to the sleep mode in step S12.

When in step S13, there is a user input or it is determined that the current time reaches a preset time, the portable terminal 120 transmits user activity pattern log data to the personal mobile terminal of a patient or guardian or an external device such as a hospital server in step S14. In step S15, the external device 130 may analyze user activity pattern log data transmitted from the portable terminal 120.

Although not shown in FIG. 15, the portable terminal 120 may provide a notification function at a time corresponding to each schedule on a schedule management list according to a preset schedule management list, through the display unit 121. The portable terminal 120 checks whether the user activity pattern data matches the schedule management list, senses an abnormal activity pattern that may cause a risky situation, and generates an alarm signal or transmit an alarm message to an external device 130 located in the activity area 10 or to a hospital server or the mobile terminal of a guardian located outside the activity area 10 when the user activity pattern data does not match the schedule management list or the abnormal activity pattern is sensed. When a schedule management message is transmitted from the external device 130, the portable terminal 12 may update the schedule management list.

In an embodiment of the present invention, the portable terminal 120 may check whether user activity pattern data matches a schedule management list and generate an alarm signal through the alarm generation unit 129 or transmit an alarm message to the mobile terminal of a guardian or a hospital server when the user activity pattern data does not match the schedule management list.

In an embodiment of the present invention, the portable terminal 120 may generate a wake-up event at a time set for each schedule on a schedule management list and change to a wake-up mode according to the wake-up event. In this case, the portable terminal 120 transmits a control message to the terminal 110 of a device 20 side corresponding to each schedule. The terminal 110 may receive a control message from the portable terminal 120, sense the approach of the portable terminal 120 and communicate with the control unit 30 of the device 20 through the communication interface 117 to automatically operate the device 20 according to the control message.

FIG. 16 is a flow chart of steps S13 and S14 shown in FIG. 15. Referring to FIG. 16, the portable module 120 activates or inactivates a wireless communication function in a preset cycle in steps S21, S27 and S29. When the wireless communication function is activated, the portable module 120 operates an advertisement function, transmits (broadcasts) a reception request message to the external device 130 and then ends the operation of the advertising function in steps S22 to S26, and S30 to S35).

When a corresponding application is executed by a user on the external device 130 such as a mobile terminal including a smart phone, signals around a user's mobile terminal are sensed therethrough, a reception request message is scanned and then the operation is ended in steps S28, S33 and S34. Next, in device connection step S36, the external device 130 senses a signal transmitted by the portable terminal 120, a user is identified through an ID of the signal, and an acknowledgement message is transmitted from the external device 130 to the portable terminal 120, and in this process, a wireless network is set between the portable terminal 120 and the external device 130.

When the wireless network is set between the portable terminal 120 and the external device 130, user activity pattern data accumulated so far is transmitted to the external device 130. That is, when the wireless network is not set between the portable terminal 120 and the external device 130, for example, when the wireless communication function is inactivated or when the wireless communication function is activated but an acknowledgment message corresponding to a reception request message is not transmitted from the external device 130, the processor 122 of the portable terminal 120 stores user activity pattern data in the memory unit 128 by utilizing the concept of “delay-tolerant” and then transmits user activity pattern data stored in steps S37 to S39 when the wireless network is set between the portable terminal and the external device 130. Accordingly, a user, a guardian or a medical team may see user activity pattern data through the external device 130.
